My first thought when reading Sohrab Ahmari's From Fire by Water: My Journey to the Catholic Faith was, “Did he write his memoir too soon?” Sohrab only converted three years ago and he's even younger than me (which, trust me, makes him very young), and some biographies do suffer from a lack of hindsight. Justin Bieber's First Step 2 Forever: My Story was written when he was just 16, and it shows.
